NOTES:

1. SUBSURFACE TRENCH DRAINS SHALL BE DESIGNED AND

CONSTRUCTED IN ACCORDANCE WITH COUNCIL'S CIVIL WORKS

CONSTRUCTION SPECIFICATION AND AUSTROADS ROAD DESIGN

GUIDELINES.

2. THE SUBSURFACE TRENCH DRAINAGE PIPE INVERT SHALL BE

LOCATED AT LEAST 250mm BELOW NATURAL PAVEMENT

SUBGRADE OR 250mm BELOW THE BASE OF SUBGRADE

REPLACEMENT LAYER OR 250mm BELOW SELECT PAVEMENT

LAYER, WHICHEVER IS LOWER, UNLESS OTHERWISE REQUIRED IN

THE APPROVED PAVEMENT DESIGN.

3. MATERIALS TO BE IN ACCORDANCE WITH THE REQUIREMENTS

OF COUNCIL'S CIVIL WORKS SPECIFICATION.

4. SUBSURFACE DRAINAGE DETAILS FOR RIGID PAVEMENTS, FULL

DEPTH ASPHALT PAVEMENTS AND HEAVILY BOUND PAVEMENTS

SHALL BE AS DETAILED ON DESIGN DRAWINGS.

5. SUBSURFACE TRENCH DRAINS SHOULD START AND END AT

DRAINAGE PITS IN URBAN AREAS. FLUSHING POINTS SHALL

OTHERWISE BE INSTALLED IN FOOTWAY OR VERGE AREAS AS

REQUIRED.

6. MAXIMUM DISTANCE BETWEEN A FLUSHING POINT AND OUTLET

SHALL BE 120m TO FACILITATE INSPECTION AND FLUSHING.

7. SUBSURFACE DRAINAGE PIPES MAY BE PLACED AT THE LOWEST

POINT IN SUBGRADE REPLACEMENT PAVEMENTS.

NOTES:

1. THE PAVEMENT DESIGNS SHOWN ARE TYPICAL PAVEMENTS

ONLY. SITE SPECIFIC GEOTECHNICAL TESTING, PAVEMENT DESIGN

AND DETERMINATION OF THE SUBGRADE CBR VALUE MUST BE

COMPLETED FOR EACH PROJECT.

2. THE TYPE, QUALITY AND THICKNESS OF MATERIAL USED IN EACH

PAVEMENT LAYER, ESPECIALLY FOR ASPHALT WEARING COURSE,

BASE COURSE AND SUB-BASE LAYERS IS TO BE DETERMINED BY

ROAD HIERARCHY CONSIDERATIONS AND THE SITE SPECIFIC

TRAFFIC LOADING (ESA). OTHER FACTORS THAT MAY AFFECT

PAVEMENT THICKNESS INCLUDE WHETHER THE ROAD IS FOR

RESIDENTIAL OR INDUSTRIAL USE AND IF THE ROAD IS A BUS

ROUTE.

3. SEAL AGGREGATE SIZE IS GENERALLY 7 OR 10mm FOR THE

CENTRAL COAST REGION, HOWEVER, THIS MAY BE AFFECTED BY

TRAFFIC LOADING (ESA), PREVAILING CLIMATIC CONDITIONS

AND CONSTRUCTABILITY REQUIREMENTS.

4. WHEN BOXING OUT, THE SIDES OF THE EXCAVATION MUST BE

TRIMMED VERTICAL TO THE FULL DESIGN DEPTH. CROSSFALL

AND DRAINAGE MUST BE PROVIDED AT THE BOTTOM OF THE

EXCAVATION TO ELIMINATE DAMMING OF WATER/MOISTURE.

5. IF SPECIFIC SECTIONS OF LOW QUALITY EXISTING MATERIAL ARE

FOUND, THEY WILL REQUIRE ADDITIONAL REPLACEMENT WORK

AND/OR USE OF GEOTEXTILES AND/OR GEOGRID.

DETERMINATION OF THE EXTENT OF THESE AREAS (IF ANY) IS TO

BE UNDERTAKEN ON SITE AT THE TIME OF EXCAVATION.

6. CARE MUST BE TAKEN TO NOT STRESS SUBGRADE MATERIAL BY

TRAFFICKING OF CONSTRUCTION EQUIPMENT.

7. SUBSURFACE DRAINAGE SHALL BE PROVIDED AT ALL

EXCAVATION INTERFACES TO ELIMINATE DAMMING OF

WATER/MOISTURE.

8. ANY AREAS TO BE WIDENED THAT ARE IN FILL SHALL BE BUILT UP

IN LAYERS USING A SELECT SUBGRADE MATERIAL UP TO THE

UNDERSIDE OF THE SUB-BASE LEVEL. EACH LAYER SHALL BE

STEPPED IN. SELECTED EXCAVATED GRAVEL MATERIALS FROM

THE SITE COULD BE RE-USED OR IMPORTED MATERIAL USED

WHERE NECESSARY.
